Tamper Discrimination in RFID Tags Using Chaotic Fragile Watermark

The novelty of this paper lies in the fact that an original chaotic fragile watermarking scheme is proposed and applied to radio frequency identification (RFID) tags. The proposed scheme not only has the ability of tamper detection but also the ability of tamper discrimination in RFID tags. The scheme can be easily plugged into existing RFID middleware applications. Theoretical analysis and experimental results show the validity of the proposed scheme.
